measuring digital signal

TG

I want to measure the time between two digital signals. Is there a command to measure this?

If you're looking for the edges of a single pulse then PULSIN will work for you.· If you have two separate pulses then you'll need to create your own timer routine:

Measure_Time:
· DO : LOOP UNTIL (Trigger = 1)····· ' wait for edge of first pulse
· DO································ ' measure width of first pulse
··· measure = measure + 1
· LOOP WHILE (Trigger = 1)
· DO································ ' measure time to second pulse
··· measure = measure + 1
· LOOP UNTIL (Trigger = 1)

The signals are from two different sources. I think I have an idea how to do it from your example. Thanks

Easy to fix it over...

Label:

IF (tri1 = 1)·AND (tri2 = 1) THEN label1

ELSEIF (tri1=1)·OR··(tri2 = 1) THEN label

ELSE label
